"It may be a brave opinion but I predict that Ubuntu Linux and Windows Vista are going to be the two operating systems that will take over the largest chunk of the desktop OS market during the next couple of years. This comparison is based on my experience with both systems during the last couple of weeks on two different computers."

I can't agree with his rating on Vista vs. Ubuntu software management. In Windows if the maker of an application releases a new version, you download it, install it, and you're done. In Ubuntu, you hope the new release gets backported (it usually isn't) or wait six months and upgrade your ENTIRE system to the next Ubuntu release in order to be able to use the new version of your application. Very, very clumsy in my opinion.
